Heya,
Perimeter = 30cm
a = b = 12 cm [Because isosceles triangle has 2 equal sides]
Perimeter = a + b + c
30 = 12 + 12 + c
30 = 24 + c
30 - 24 = c
6 = c
s = P/2
s = 30/2
s = 15
Area = √s(s-a) (s-b) (s-c)
Area = √15 (15-12) (15-12) (15-6)
Area = √15 × 3 × 3 × 9
Area = √15 × 3 × 3 × 3 × 3
Area = 9√15 cm^2
Hope my answer helps you :)

Shobana
